PaitentedApr. 8, 1913.-

Application filed September 21, 1912. 'Serial No: 721,710.

The invention relates to improvements in demountable rim lockingapparatus and has particular reference to a lock provided with asupporting means rigidly mounted on a fixed annular rim, a means mountedin said rim and engaging said lock for placing into position a floatring capable of expansion and contraction for holding permanently intoposition a demountable rim structure.

In the following is described in connection with the accompanyingdrawings one embodiment of the invention the features thereof being moreparticularly pointed out hereinafter in the claims. I

In the drawings Figure 1 is a cross sectional view of the fixed rim anddemountable rim and a vertical-sectional view partly in elevation of thelocking means thereof;Fi'g. 2 is a faceelevation of said locking meansillustrating the position the same assumes in connection with the fixedrim; Fig. 3 is a detailed face elevation of the locking head; Fig. 4 isa plan view of said locking head, and Fig. 5 is a detailed elevation ofa modified form of-floating ring lockingmeans.

Similar numerals of reference indicate similar parts throughout theseveral views.

In the drawings (1) indicates a felly having rigidly mounted thereon afixedrim (2) having formed therein at its front edge an annular groove(3) and at its rear edge a compound retaining wall (4) (5) indicates thebase member of a demountable rim provided at its rear edge with areinforcing flange (G) engaging retaining wall (4:) on fixed rim (2.)and said demountable rim (5) havingformed thereon adjacent to-saidreinforcing flange (6) a supporting or retaining shoulder (7) adapt-- edto receive a supporting tire'retainmg ring Said rim (5) has formedtherein at its forward edge a depending channel (9) 1 provided with alower engaglng locking surface (10) resting on the edge of rim (2) atapoint where said rim (2) depends lnto groove and immediately ad acent tosaid depending channel (9.) an upwardly progect-lng' annular r1b.(1.1)and at the'extreme outer edge of said rim an overlapping flangeorhousing (12). Said up wardlv pro cct1ng annular rib (11) receives one ofsaid flanges (11) being-adapted to said flanges being adapted to engagethe upper outer surface of the overlapping flange or housing (12) of rim(5). This only strengthening the supporting facilities of the separabletire ring (13), but further insures the supporting facilities ofthe rib(14) as well as the outer body of rim (5) in its entirety.

separable ring (13) is split and at such split ends a spring pin (15) isinserted through suitable apertures therein engaging a correspondingaperture in rib (11.) for holding the same permanently into place on thebase member (5) of the demount'able rim. Fixed rim (2) has formedtherein an aperture adapted to receive the depending end (17) of lug(18) which is spot welded .on the under surface of the base member (5)of the demountable rim, the object of which is to prevent thecircumferential creeping of the demountable rim structure as a whole.

and free to move annularly with relation thereto a floating-ring (19)provided with free ends having cut therein a slot (20) adapted toreceive one end of levers (21) 'which are pivotally mounted therein theother ends of saidlevers (21) being pivot; ally mounted as at (22) inthe flanges of locking head (24;).

The locking head (21) has formed therewith a laterally projectingsupporting body (25) having cut therein an aperture (26) adapted toreceive a locking sleeve (27) provided with a hexagonal head (28) saidsleeve being internally threaded to engage the threaded supporting stud(29) the upper end of said stud being flattened out as in (30) and spotwelded to the inside surface said threaded stud becomes a rigidlysupporting means as associated withthe fixed rim.

The base wall of groove (3) has cut thereseparable tire retaining ringwhich is. provided with two depending flanges (11-);

projectinto channel (9) and the other of type of structure provides ameans of not- Annular groove (3) has mounted therein of the wall ofgroove at which point in apertures th ugh which the flanges o aftsub-seal the inside engaging surfaces of both the fixed run anddemountable run, as well as-the looking meanstherefor,

With reference to Fig of t is drawings the float-ing'ring (19} hasformed on its re spective ends thereot depending lugs (32) havingmountedin their lower ends thereof levers"'(33 pivotally mountedtogether at their ends (3 i),'one of said lugs (32) havingpivotallymounted herein a earn lock (35) at (36). flSaid cam lock (35) hasformed,

therein an aperture (87) adapted to receive the'endof asuitabletooliorexpanding and contracting the floating ring (19) withr'elation to; ,fix'ed rim anddemountable rim.

' It is o vious that the devices herein shown and de'soribed may bewidely varied without departing from the spirit of the invention, i

What we claim and desire to secure by Letters Patent of the UnitedStates is 1. A devicebf the character described comprising a fixed rimhaving formed thereinat one-edge an annular groove and at its oppositeedge a retaining reception shoulder, a floating ring mounted in saidannular groove and freeto move circlnnferentially with relationther'etlinks mounted in the ends of said floating ring, a supporting studrigidly mounted on the outer surface of groove "of said fixed-rim, alocking sleeve movable on said stud, a locking head carried by saidlocking sleeve provided with flanges adapted to project into saidannular groove having associated therewith means for reeeiving theopposite ends of said links carrierl'hy said floating ring.

2. A- device ofvthe character described noes m1 comprising a fixedannular rim provided at ried by said locking sleeve provided withupwardly'projecting flanges provided with means adapted to receive theopposite ends of said links carried by said floating ring,

said locking head being adapted to cover the apertures of said fixed rimwhen in its locked position.-

3. A device of the character described including a locking means fordemountable rims comprising a supporting stud rigidly mounted on theouter surface of a fixed rim, a locking sleeve movable vertically onsaid supporting stud,-a locking head carried by said locking sleevemovable vertically therewith having formed thereon vertically projectingflanges, a floating ring mounted in said fixed rim and free to movecircumferentially a limited distance with relation thereto and providedwith free ends, links pivotally mounted in the free ends of said ring,the opposite ends of said links being 'pivotally mounted in saidvertically projecting flanges on said locking head.

In testimony whereof we have hereto signed our names in the presence oftwo subscribing witnesses.
